[Geoserver-users] GeoServer with non-spatial SRID?

Hello,

I’m new to GeoServer and GIS.
I would like to use GeoServer for creating a geometric application, which works on euclidean metric data. In general, this shouldn’t be a problem, because there is a lot of geometric stuff build into GISs. But GISs are build on a model of the earth and thus coordinates refer to points on an ellipsoid.
For my application I want to create “maps” of smaller territories, like the floors of a building. These are already “projected” and I don’t need any projection. At this point I’m evaluating, if this could be realized by using a GIS infrastructure, instead of redeveloping the most of such a system.
So can anyone tell me, if this could be done, or where the best point to start with this?
Maybe it could be enough to create my own SRID, which could be reused through PostGIS, DB2 and GeoServer?

Thanks for your help,
Jan

Well, our referencing subsystem is in fact able to handle pure cartesian
data, but it's not well tested in this environment.
The EPSG database defines a couple of sample local coordinate systems
that can probably be used as an example:

EPSG:5807
LOCAL_CS["EPSG local engineering grid example B",
   LOCAL_DATUM["EPSG example Platform Y", 0, AUTHORITY["EPSG","9313"]],
   UNIT["m", 1.0],
   AXIS["Plant East", NORTH_EAST],
   AXIS["Plant North", NORTH_WEST],
   AUTHORITY["EPSG","5807"]]

So I guess you can try stamping your data as EPSG:5807 and see what
happens.

Define infrastructure... if you are just using GeoServer and a WMS
client it may be that everything works fine, if you're using also
desktop clients such as uDig, I don't know, things would have to be
tested as such.

Yep, or you can try using EPSG:5807 directly and see what happens.
